I'm a little confused about the namelist files. There are 4 of them in the "static" directory (of my arw run) - where do I set start and stop times for runs? These seem to have been created from some other master file - I don't think I have to edit all 4 of these... I checked the data/domains/arw/static but that holds a different time than my simulation. There wasn't a time of run setting in dwiz...

Don't touch those namelists if you want to use EMS features. If you want to work with namelists directly, then you have to forget about EMS and do your scripting yourself.

WRF EMS scripts create dynamically namelists and you don't need to worry about how. Only if something doesn't work as you like, then you can hack the scripts, but again, not namelists directly.

If you want to use EMS system as it is, then you should go through users manual first. There you will find all information about how to start and configure your runs. Look also at directory wrfems/runs/<domainname>/conf - everything that you need to set about your run is there

Thank you for the reply! I didn't want to hack EMS but I thought I saw a post on here requesting a namelis, which made me think that occasionally these were to be modified. Of course, I went through the users manual ~1.5 times so far - finished it last night - obviously forgot most of it. My mind is swimming - lots of stuff I didn't understand very well, but it helps my understanding quite a lot to exercise the software - I understand things that didn't make sense by just reading words.

I should have mentioned I'm trying to reproduce this event:http://www.youtube.com/watch?v=wk70fAQG6c8
(or else the 8 July 2002 storm)
...just as an exercise in actually using the software and getting decent outputs. I'm looking for suggestions on which --dset's would be needed.
Thanks Again

With those 5 files you will be able to run 24h simulation starting at 2012-09-11, 00 UTC and ending at 2012-09-12, 00 UTC.

When you download these at your computer, create domain with dwiz around area where you want the simulation. I recommend that you first try without nesting, use ARW core at around 12km resolution.... also go into wrfems/runs/<domainname>/conf and configure your run as you like. Conf files there are pretty much commented so you won't have much trouble doing that.

When you create domain, put downloaded files into wrfems/runs/<domainname>/grib directory.

Then you have to ensure that gribs file names and naming convention for FNL dataset matches. So you need to check wrfems/conf/grib_info/fnl_gribinfo.conf file. There you will find sumething like:

You ARE the best! Thank you for your help. I'm going to start that run and hit the manual again. I still have to get a couple more softwares installed. My colleague is trying to install CESM, but I like WRF/GEOS5/ModelE. But we do need CESM because it can actually reach the thermosphere and my colleague does satellite/debris orbits and orbit decay (I do cloud remote sensing from orbit). - Patricia

EDIT: I meant to ask - the EMS scripts aren't "smart" enough to automatically download the files needed from that repo?

I don't know about 0.5 deg yet. They are smart enough for FNL 1 deg, but only with wrfems 3.2 beta. In 3.1 everything should be downloaded manually (it's not very hard )

Hey, did you know that "--local --analysis" are not options
to ems_autorun. Try again or run "ems_autorun --help" for
assistance.

Remember, there are no bad options, just those that will
result in this message again.

Just on a whim, I tried
patti@OS121-> ems_prep --dset fnl --date 20100911 --cycle 00 --analysis
...but the script doesn't try to connect to the online fnl dataset - it tries to FTP to "local" - maybe because of the first time when I used the --local flag with autorun? I'm looking for how to remove the "local" from the FTP command because I *know* the software scripts know about the fnl database.
